Bottom Line Up Front: Eclipse Neon content assist (Ctrl+space) does not offer any proposals for my JavaScript code.
Here is what I've checked so far:
- JSDT has been installed
- "JavaScript resources" include ECMASciptBuilt-In Library, ECMA 3 Browser Support Library, jQuery
- The project's Include path has ECMAScipt Built-In Library, ECMA 3 Browser Support Library, jQuery, and JavaScript Web Project support
- Eclipse's JavaScript Content Assist is enabled and includes Basic proposals, Other JavaScript Proposals, Template Proposals, and word proposals.
- I changed the content assist from ctrl+space to ctrl+0 to check whether ctrl+space had been hijacked
- Content assist DOES work with regular Java (in a different project)
- I tried reset to defaults under Content Assist > Advanced
- JavaScript facet is selected for the project
- .js files and .jsp files are stored in folders that are under folders that are designated as source folders in the project properties under JavaScript > Include Path
- This is also an issue in Mars 2.
- I've run through the steps listed here for configuring content assist: http://www.eclipse.org/pdt/help/html/using_javascript_content_assist.htm
The content assist isn't even proposing functions that are defined within the same .js file. How can I get Eclipse's content assist to propose elements correctly?
I have the same problem and it seems to be a known bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=504057
+1 not working in Eclipse Neon. As an alternative you may try Netbeans 8. Javascript is working good there. I don't know what happened to Eclipse but php and Js support is poor.
P.S. Just downloaded Eclipse Mars - can confirm that it's working fine.
I've met this situation before,and then I found that if the js file is in a "normal java project",then it won't come uip with content assist,but if the js file is in a "dynamic web project",then the content assist just work well,hope it will help.
